X2. Stuff comes in sheets. Made a template out of an old manilla folder to mark foam for cuts. I used an old metal ballpoint pen cap to make holes for backing plate studs.
The small hole cuts can be made with any sharp cutting instrument. To make a small round hole easily, I recommend using a die, or something like it. My attempts to make a small round hole with scissors and knives (yes, even an exacto) did not yield satisfactory results.
Failing to find something I already have to do the job, I would have gone out and purchased a grommet kit. The kit will include a die that will make a perfectly round hole with one whack of a hammer. Lowe's has them for about $6.32 (just looked on line). The part of the kit needed is called the hole punch. They come in 3/8 and 1/2 inch sizes.
